Mulie my only couple of expriences with swaps have been a mark v 300 to 7stw at bartlien that was a 30" heavy CT about $800 out the door shipped back to me turnkey deal.
Another was pac-nor ruger 1 ran about the same with the blue finish. Both scenarios I had more affordable and more expensive options seems like.
This particular rifle was done by someone else, my guess it wasn't cheap with sights and finish - just depends on what all your looking for. Many of them have websites you can go on surf and ask questions - several others the two i mentioned I would recommend, customer service was easy to deal with. Looking to have one of my southpaw rifles taken to a 220 swift, prob do that in the off season i've discussed with pac-nor. Like anything else the most customized you get it the more it will run. Just a vanilla SS barrel with standard twists aren't going to be terrible. Someone else may chime in, that's just my experiences.
